A Fiber Connection (FICON) information unit is received by a host processor executing a host internet protocol (IP) software library. The FICON information unit is written to a transport layer. Data including the FICON information unit is then transmitted to a storage control unit over an IP network.

Emulating FICON over IP

A method includes tagging, by a processor executing a first operating system kernel, a region of a memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decoupling the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.

Port throttling across an operating system restart during a hot upgrade

A method includes tagging, by a processor executing a first operating system kernel, a region of a volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decoupling the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the volatile memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.

For block based end-to-end data protection for extended count key data (ECKD) in a computing environment, information units (IU's) are aligned in a block boundary format. Block protection trailer data is added to each one of the IU's.

Blocked based end-to-end data protection for extended count key data (ECKD)

A method includes tagging, by a processor executing a first operating system kernel, a region of a volatile memory coupled to the processor, and initiating a boot of a second operating system kernel while preserving in the volatile memory contents stored therein. Following the boot of the second operating system kernel, a set of parameters referencing the tagged region is retrieved from the volatile memory, and the tagged region is then used, based on the retrieved set of parameters.

Memory tagging and preservation during a hot upgrade

A processor, executing a first operating system kernel, tags a region of volatile memory coupled to the processor, and initiates a boot of a second operating system kernel while preserving in the volatile memory contents stored therein. Following the boot of the second operating system kernel, a set of parameters referencing the tagged region is retrieved from the volatile memory, and the tagged region is then used, based on the retrieved set of parameters.

A processor, executing a first operating system kernel, tags a region of volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decouples the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the volatile memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter.

Exemplary method, system, and computer program product embodiments for block based end-to-end data protection for extended count key data (ECKD) in a computing environment are provided. In one embodiment, by way of example only, information units (IU's) are aligned in a block boundary format. Block protection trailer data is added to each one of the IU's. Additional system and computer program product embodiments are disclosed and provide related advantages.
